Publised in the Transaction of IEEE.GRS in June, the paper titled 'Three-Dimensional Reconstruction of Man-Made Objects Using Polarimentric Tomographic SAR', unveiled that the major progress in the 3D imaging for radar objects has been made by NUDT's research group. The resolution, obtained based on the multiple-measurement vector compressive sensing model and Tikhonov regularization theory, is 0.45m according to the paper, wchich is the highest one achieved in the world nowadays.
